ROPS deficiency of gray-market tractors.
Many used tractors that are imported from Japan are adding to the current national inventory in the U.S. and Canada of farm tractors that lack a rollover protective structure (ROPS). Gray-market tractors are built for use by the manufacturer for a certain country but are imported against the manufacture's wishes to a second country for use there, usually as a used tractor.

متن کاملPrevalence of ROPS-equipped tractors on minority operated farms in the US.
BACKGROUND Tractor overturns kill an average of 100 farmers and farm workers per year. Roll-over protective structures (ROPS) are a proven intervention, but are not on a sufficient number of tractors in the US to reduce these deaths. Little has been reported on ROPS use by racial minority farm operators. METHODS Data from the NIOSH OISPA survey were used to assess ROPS prevalence rates from a...
متن کاملFactors associated with the prevalence of non-ROPS tractors on farms in the U.S.
Rollover protective structures (ROPS) are an effective engineering control known to prevent tractor overturn deaths, the leading cause of occupational fatalities for farmers and farm workers in the U.S. However, the use of ROPS is known to vary greatly from farm to farm. A national sample of 11,458 farm operators from the 2004 Occupational Injury Surveillance of Production Agriculture (OISPA) s...
متن کاملVerification of the IBM RISC System/6000 by a Dynamic Biased Pseudo-Random Test Program Generator
Verification of a computer that implements a new architecture is especially difficult since no approved functional test cases are available. The logic design of the ISM RlSC System/SOOO" was verified mainly by a special1 developed random test program generator (RT PY G), which was used from the early stages of the design until its successful completion. APL was chosen for the RlSC System/SOOO R...
متن کاملDevelopment and validation of a computer program to design and calculate ROPS.
In Spain, there are more than 250,000 tractors built before 1980, when it became mandatory for all new tractors to be equipped with a rollover protective structure (ROPS). A similar situation is found in the European Union, but the situation is worse in the U.S. and in developing countries. Directive 2003/37/EEC establishes that tractors over 800 kg weight can be homologated by using the OECD s...
